Abstract
Methods and systems for adjusting a force feel profile of an inceptor of an aircraft are provided. The force feel profile is based on a baseline value of an operating parameter of the aircraft and defines an amount of resistive force applied to the inceptor as a function of displacement of the inceptor. An embodiment of the method includes receiving data indicative of a current value of the operating parameter. Based on a difference between the current value and the baseline value of the operating parameter, a portion of the force feel profile corresponding to a range of displacement values is shifted to adjust an amount of resistive force defined by the portion of the force feel profile for the range of displacement values.
